 * crewx hook install — Register crewx-hook-dispatch as a PreToolUse hook
 * in <projectRoot>/.claude/settings.json and/or <projectRoot>/.codex/hooks.json.
 *
 * Security:
 *   - Prompts user before modifying settings (R1)
 *   - Uses absolute path for crewx binary (PATH manipulation prevention)
 *   - Backs up original settings files
 *   - Preserves existing user hooks
 *   - Never traverses parent directories — project root determined by crewx.yaml
